<!--
|
|
This field tracks the location bar state. The value that the user typed
|
|
in to the location bar may not be changed while this field is zero.
|
|
However invoking a load will temporarily increase this field to allow
|
|
the location bar to be updated to the new URL.
|
|
|
|
Case 1: Anchor scroll
|
|
The user appends the anchor to the URL. This sets the location bar
|
|
into typed state, and disables changes to the location bar. The user
|
|
then requests the scroll. loadURIWithFlags temporarily increases the
|
|
flag by 1 so that the anchor scroll's location change resets the
|
|
location bar state.
|
|
|
|
Case 2: Interrupted load
|
|
The user types in and submits the URL. This triggers an asynchronous
|
|
network load which increases the flag by 2. (The temporary increase
|
|
from loadURIWithFlags is not noticeable in this case.) When the load
|
|
is interrupted the flag returns to zero, and the location bar stays
|
|
in typed state.
|
|
|
|
Case 3: New load
|
|
This works like case 2, but as the load is not interrupted the
|
|
location changes while the flag is still 2 thus resetting the
|
|
location bar state.
|
|
|
|
Case 4: Corrected load
|
|
This is a combination of case 2 and case 3, except that the original
|
|
load is interrupted by the new load. Normally cancelling and starting
|
|
a new load would reset the flag to 0 and then increase it to 2 again.
|
|
However both actions occur as a consequence of the loadURIWithFlags
|
|
invocation, which adds its temporary increase in to the mix. Since
|
|
the new URL would have been typed in the flag would have been reset
|
|
before loadURIWithFlags incremented it. The interruption resets the
|
|
flag to 0 and increases it to 2. Although loadURIWithFlags will
|
|
decrement the flag it remains at 1 thus allowing the location bar
|
|
state to be reset when the new load changes the location.
|
|
This case also applies when loading into a new browser, as this
|
|
interrupts the default load of about:blank.
